Category: Taranis

I stumbled on a nifty feature where you can use your Taranis to flash your receiver firmware, all you need is the supplied smart port cable, no programmers, or software.

One of the reasons you might want to do this is to update newer firmware to fix bugs with one of your receivers, or add functonallity, like updating your X4R-SB to support PPM as well as SBUS channel outputs.

I’ve had a few questions from people on how to upgrade their firmware to get the Taranis RSSI laptimer working. There are a few different ways to do it, I will be showing the method I think is the simplest.

If you are looking for a free RSSI based lap timer for your Taranis or opentx radio then this might be what you are looking for. There are some very impressive lap timing systems already out there, but found that for my purposes they were either were too complex for my needs, or didn’t have all the features that I wanted. Specifically I wanted the timer to

be simple to use

trigger lap times using RSSI signal

verbally tell you your lap times

save a log of the times if I wanted to

There has already been a lot of excellent systems built out there, and decided to modify an existing project that *almost* did everything I wanted which can be found at Jeremy Cowgars very excellent opentx laptimer.
